A tonometer refers to the equipment that is used in tonometry – a test that measures the pressure inside your eyes, also known as intraocular pressure or IOP for short. Tonometry is rarely performed at your average comprehensive eye exam unless you are at high risk of or have been already diagnosed with glaucoma. Fortunately, tonometry can be used to detect changes in eye pressure before they cause any symptoms, enabling prompt action to be taken before your vision is affected.

About Glaucoma

Glaucoma is a common eye condition that occurs when the optic nerve, which connects the eye to the brain, becomes damaged. It’s normally caused by fluid building up in the front part of the eye, which causes the pressure inside the eyes to build. As the pressure increases, the optic nerve becomes increasingly damaged, and this prevents messages from being transmitted between your eyes and brain effectively. As a result, the patient’s vision becomes compromised. Without treatment, the level of vision loss will continue to increase. Unfortunately, any vision that has been lost as a result of glaucoma cannot be restored.
 

Most of the time, glaucoma develops very slowly which means that many people don’t realize that they are affected until some damage to their vision has already occurred. However, occasionally glaucoma can develop quickly, and symptoms do occur.

These can include:

• Red eyes

• Intense headaches

• Tenderness around the eyes

• Eye pain

• Seeing rings/halos around lights

• Blurred vision

• Nausea and vomiting

If you notice any of these symptoms, it’s important that you make an appointment with your eye doctor right away so that you can be assessed. You are likely to have a tonometry test as part of this assessment.
 

What to expect from tonometry testing

There are various methods of tonometry testing, but many eye doctors use either Goldmann tonometry, which is the conventional technique to measure eye pressure, or electronic tonometry.
 

Goldmann tonometry testing is carried out using the Goldmann applanation tonometer, which is attached to a slit lamp microscope. This requires anesthetic eye drops to be used which numb your eyes, before a small probe is pressed gently against the eye, indenting the cornea. The pressure that the cornea pushes back onto the tonometer is what is measured to give your IOP reading. Electronic tonometry is where a handheld, mobile device is gently and quickly applied to the cornea to check the pressure, providing an accurate reading. Some eye doctors also offer non-contact tonometry which is where a puff of air is used to flatten the cornea, although this is reported to be less accurate than the Goldmann technique.

Eye care professionals use Optikam’s technology to capture more than 3 million eyewear measurements every year. The OptikamPad iPad app is a total dispensing solution that enables eye care professionals to successfully assist patients at all stages of the eyewear dispensing process, providing them with a unique and custom patient experience.

Optikam Posture Devise (OPD)

You may be surprised to learn that wearing glasses can and likely will affect your posture. Glasses lenses are most accurate when you look directly through their center. This means if your glasses are sitting too low or have slipped down your nose, you may find that you are subconsciously tilting your head back and this can affect your overall posture.

Optikam’s OPD measurement device is a cutting-edge tool that obtains eyewear measurements that take into account how the frame will be worn by patients, enabling the fit to be customized to their individual parameters. The ten measurements taken into account when determining each patient’s position of wear include:

• Monocular pupillary distance

• Multifocal seg heights

• Pantoscopic tilt

• Rear vertex distance

• Wrap (face form tilt)

• Near pupillary distance

This results in frames that not only look fantastic, but that also fit perfectly, remaining both comfortable and stable on the face without you needing to adopt an unnatural posture. The measurements obtained by the Optikam OPD measurement tool are immediately visible on your eye doctor’s tablet so that they can recommend which alterations to the frames are needed to ensure that the frames fit with precision and gives you the best visual experience.

Benefits of OptikamPad and Optikam OPD

Traditionally, the process of a comprehensive eye exam, choosing frames and fitting glasses requires fairly close contact with your eye doctor or other eye care professionals. However, with social distancing being a new process variable, many patients are looking for more virtual options. Fortunately, OptikamPad makes it possible for optical stores to dispense eyeglasses with minimal human contact. This is because the OptikamPad can take measurements from a further distance or even through plexiglass screens. It can even be placed on a stand and the app operated using a Bluetooth mouse, putting even greater distance between your eye care professional and you.

Neurolens are the first and only prescription lenses that include an element of contoured prism in their design. This prism is designed to bring the patient’s eyes into more equal alignment, and this should help to provide relief from the symptoms that are associated with several eye misalignment conditions, including digital eye strain and binocular vision dysfunction.
 

What is digital eye strain?

Digital eye strain is the name given to describe a group of symptoms that can occur when someone spends long periods of time using digital devices. Since using digital devices requires the eyes to work harder than normal and we don’t always position our devices the perfect distance away, it can lead to issues such as eye pain, dry and irritated eyes, eye fatigue, light sensitivity and blurred vision. Unsurprisingly, the number of people who are experiencing digital eye strain has grown significantly over the last few years and is expected to continue to do so.

What is binocular vision dysfunction?

Binocular vision dysfunction, also known as BVD for short, is another eye condition but is one that is very misunderstood. Binocular vision dysfunction occurs when the eyes aren’t perfectly aligned, causing your brain and eyes to work harder than normal in order to create a clear visual image and remain focused. This places pressure on the trigeminal nerve, which is the nerve that is responsible for the majority of the sensations that we experience in our head and back. BVD can often manifest as other things owing to the huge range of symptoms that are associated with the condition. These can include, but aren’t limited to:

• Blurred vision

• Headaches/migraines

• Double vision

• Motion sickness

• Vertigo

• Dizziness

• Anxiety

Many people don’t think to visit an eye doctor when they are experiencing these symptoms, but all can occur simply because the eyes are out of alignment.

What are Neurolens lenses and how do they help?

As well as containing your usual prescription, Neurolens lenses also contain a specific amount of contoured micro-prism. This micro-prism alters the position of images so that they are aligned in the same plane. This then reduces the pressure on the muscles around the eyes as well as bringing the eyes into alignment, easing the symptoms that the patient has been experiencing.

The amount of prism in Neurolens lenses is decided using the Neurolens eye-tracking device. This non-invasively measures the misalignment that the patient is experiencing, and this is used to form the basis for the patient’s Neurolens prescription. After this, it’s fairly normal for the amount of prism to need to be adjusted by infinitesimal amounts to achieve the optimal relief from your symptoms. Most patients who choose Neurolens treatment see a 50% improvement in their vision as soon as they start to have micro-prism incorporated into their prescription lenses. However, with careful adjustments, many patients see as much as an 80% reduction in the effects of digital eye strain and binocular vision dysfunction.

Our eyes are extremely delicate, yet they can be subjected to harsh conditions and other environmental factors that affect their health. One of the problems that can affect our eyes is an accumulation of dirt, debris and bacteria on the eyelids. This can cause a range of issues, including stopping tear film from reaching the eyes and being properly dispersed over their surface – which is necessary to keep them healthy and comfortable. Fortunately, a new solution called BlephexÔ can help.

What is BlephexÔ?

BlephexÔ is a handheld electro-mechanical device that is applied to the margins of the eyelids with the purpose of cleaning them and improving the effectiveness with which tear film flows onto the surface of the eyes.

BlephexÔ has a disposable, surgical-grade sponge tip which rapidly oscillates to create a cleaning action. Before the sponge tip is placed onto the eyes, it is soaked in a gentle exfoliating solution. This solution provides soft abrasion to help remove dead skin cells and debris that could be irritating the eyes and interrupting tear film progression. The BlephexÔ device is manually applied to the eyes and moved gently across the eyelids, with the entire, painless process taking approximately 6 to 8 minutes per eye. A different sponge is used on each eye, ensuring that no bacteria is passed between them. After the procedure, patients are given instructions on how to maintain the cleanliness of their eyelids with daily/nightly eyelid hygiene at home.

Most patients experience a significant improvement in tear film production and dispersal, and a reduction in unpleasant symptoms that they may have been experiencing within 48 hours of their treatment. While a single treatment is normally enough to produce excellent results, many patients are advised to have BlephexÔ every 4-6 months.

What conditions can BlephexÔ help with?

BlephexÔ can be used to clean the eyelids at any time, and people who suffer from dry eyes or eye allergies may find it is particularly beneficial for helping to reduce the symptoms that they experience. It can also be combined with Lipiflow – another technological solution – to help counteract the effects of dry eyes.
 

Unsurprisingly, BlephexÔ is particularly recommended as a treatment for an eye condition called blepharitis. Blepharitis is characterized by the inflammation of the eyelids, which causes them to become red, swollen and itchy. Although the condition is not usually serious, it can lead to further problems if it isn’t treated.
 

Symptoms of blepharitis include:

• Sore eyes

• Itchy eyes

• A gritty, irritated feeling affecting the eyes

• Redness

• Flakes or crustiness around the roots of the eyelashes

• Eyelids that stick together when you wake up in the morning

If you are suffering from the symptoms of blepharitis, dry eyes or eye allergies and feel that you would benefit from BlephexÔ treatment, please contact our team to schedule a consultation appointment.

We all want to look our best and in the last decade, we have seen a significant increase in the number of people seeking cosmetic services in order to enhance their appearance. With our eyes being our most distinguishing feature, we want to make the most of them. Thankfully there is now a range of cosmetic services that can help to rejuvenate our eyes and the area around them to keep them fresh, young and wrinkle-free. 

Let’s take a look at some of the services on offer.
 

Pigment removal

The brown pigment spots that appear on the face are often referred to as age spots and are a result of sun exposure. With age, the repeated exposure to UV rays causes melanin, a compound that is responsible for pigmentation and protecting the skin begins to clump together to form an area of hyperpigmentation. Whilst they aren’t any cause for concern, many people feel that they look unsightly. Luckily, there are a number of different treatments that you can get to remove them including topical creams, laser therapy, and chemical peels.

If you are suffering from darker pigmentation then we strongly recommend that you make an appointment with a qualified dermatologist who will recommend the best course of treatment for you, based on your specific needs.
 

If you are one of the thousands of people considering LASIK laser eye surgery, then you will probably be gathering as much information as possible about the treatment. By this point, you are probably aware of the benefits that LASIK offers, such as a reduced or eliminated need for glasses or contact lenses and greater convenience in your day to day life. However, for many patients, despite the advantages of LASIK, the thought of surgery on their eyes is still a cause of anxiety and fear. One of the best ways to alleviate this concern is to find out more about what the procedure entails.
 

Your consultation

Before you can be approved for any form of laser vision correction, including LASIK, you will need to attend a consultation appointment with your surgeon. During the consultation, he will perform an examination of your eyes and use your medical and ocular history to determine if you are a good candidate for the procedure. He will also speak to you about the expected outcome from your surgery, making you aware that while LASIK will dramatically improve your eyesight, there is no guarantee that you will not need to wear glasses in some situations, such as while driving in the dark. 
 

How LASIK Works

LASIK uses a cool, ultraviolet beam of light to reshape the patient’s cornea. Doing so will more accurately focus the light that enters the eye on to the retina, thus improving the patient’s vision. The way in which the cornea needs to be reshaped will depend on the visual needs of the patient. For example, a patient who is far-sighted will need their cornea reshaping to be steeper to experience better eyesight. Alternatively, a patient who is near-sighted will require their cornea to be flattened in order to improve their vision. LASIK can also smooth an irregular cornea into a more standard shape, meaning that the procedure can also be used to correct astigmatism.
 

The LASIK procedure

The LASIK procedure is very fast and straightforward. Although you will probably be in the surgical suite for around half an hour, the actual process only takes a couple of minutes per eye. The rest of the time will be spent preparing and ensuring that you are comfortable. Anesthetic eye drops are given to patients before their procedure so that the entire process is pain-free. If you are particularly anxious, it may also be possible for you to be slightly sedated – this should be discussed with your doctor at your consultation appointment.

Once you are in position, we will use a femtosecond laser to cut a thin, circular flap into the outer cornea. This can then be pulled back to reveal the underlying corneal tissue, known as the stroma so that it can be reshaped using the laser. The exact path that the laser needs to take, known as the topography, will have been pre-programmed ahead of the procedure and can be followed with complete precision and accuracy.

Once the reshaping is complete, the flap is replaced back over the eye and the surgery is complete. There is no need for sutures or bandages as the cornea will start to heal immediately and without any medical intervention.
 

If you already rely on wearing glasses or contact lenses to be able to see clearly, you may be frustrated with the effect that they have on your life. Regular vision tests, finding glasses to suit your face shape, having to remember to take eyeglasses with you wherever you go, prescription sunglasses, fiddly contact lenses… the list of inconveniences associated with conventional ocular solutions is extensive. 

LASIK is a modern, minimally-invasive procedure that can substantially reduce or eliminate your need to use eyeglasses or contact lenses, allowing you to enjoy life without limitations or inconvenience. The popularity and success of LASIK laser eye surgery have helped to make it the number one elective surgery across the globe. 
 

Candidacy for LASIK

LASIK has an extremely high success rate. According to the American Society of Cataract and Refractive Surgery, 96% of patients achieve 20/20 vision or better. However, it’s high success rate doesn’t make LASIK automatically the right solution for everyone.

Candidacy for LASIK is assessed by our doctors on a case by case basis so that you be certain that whatever treatment is recommended for you, it will give you the very best opportunity to improve your vision. During your consultation, our doctors will perform a thorough examination of your eyes and vision, ask you about your general health and talk you through both the procedure and aftercare.

The general guidelines for LASIK candidacy state that patients must:

• be at least 18 years of age

• have had stable vision with no prescription changes for a minimum of 12 months

• have a current prescription for eyeglasses or contact lenses that falls between specified parameters (Our doctors will be aware of what these parameters are)

• have no significant medical or eye-related problems such as glaucoma, macular degeneration or diabetic retinopathy

• have no history of corneal disease

• not be pregnant or nursing at the time of the procedure

If you thought that just laser eye surgery was impressive, then be prepared to be astounded by the arrival of iDesign custom Lasik. iDesign is the most advanced wavefront-guided laser treatment available. The system creates a uniquely accurate measurement of the entire optical system that can be relied upon completely without any guesswork. This is then used to create a highly detailed topography or map of your eye, making it easier for your surgeon to pinpoint the areas that need addressing with pinpoint precision. 
 

How accurate is iDesign?

iDesign is extremely accurate due to its diagnostic equipment that is able to determine 1,257 different micro eye prescriptions. Each one of these will measure the eye prescription to 0.01 of a dioptre strength – 25 times more than what a regular prescription for glasses or contact lens prescription is measured to. 
 

Who is iDesign suitable for?

While iDesign Custom Lasik can benefit almost any patient with refractive problems, it is particularly beneficial for people who have unusual corneas or have had eye surgery in the past. 
 

Is it painful?

Laser eye surgery is generally considered a pain-free procedure by the majority of patients. Anesthetic eye-drops are used to numb the outer area of the eye during the course of the surgery. Once these have worn off, some patients do experience some mild discomfort during the days following the procedure, but over the counter pain relief is usually sufficient to relieve this.
 

Astigmatism is a relatively common eye disorder that causes the vision to be blurred or distorted. It occurs when the lens part of the eye, known as the cornea, isn’t perfectly curved and instead resembles a football rather than a soccer ball. This means that the light entering the eye comes through at a distorted angle, making the object appear blurry and out of focus. There are several ways in which it is possible to treat astigmatism, including laser eye surgery and corrective lenses. However, another possibility is a solution referred to as limbal relaxing incisions.
 

What are limbal relaxing incisions?

Limbal relaxing incisions are microscopic cuts to an area in the eye known as the limbus. This helps to relax the curve in the cornea and improve its ability to focus light correctly. It can significantly improve your astigmatism and the overall quality of your vision.
 

Am I a good candidate for limbal relaxing incisions?

If you have astigmatism, are over 18, in good general health and have no major eye conditions, then chances are you are a good candidate for limbal relaxing incisions. Make an appointment with your eye doctor to discuss your candidacy further.

A refraction test, also called a vision test, is usually performed as a part of a routine eye examination. The purpose of this test is to determine if a person has a refractive error which would then mean the patient would need glasses or contact lenses.
 

What Is The Normal Value for Refraction Test?

A value of 20/20 is normal (optimum) vision. This means that individuals who have 20/20 vision are able to read letters that are 3/8-inch (1 centimeter) tall from 20 feet (6 meters) away. The normal uncorrected vision (without glasses or contact lenses) refractive error is zero (plano). Individuals who don’t have 20/20 vision, have what is called a refractive error. A refractive error means that the light is not bending properly when it passes through the lens of the eye. The refraction test will tell the doctor what prescription lens should be used in order to have 20/20 vision.

For people over age 40 who have normal distance vision but difficulty with near vision, a refraction test with a small type size is used to determine normal near vision and the correct power of reading glasses.
 

How Is The Refraction Test Performed?

The test is performed by having the patient seated in a chair that has a special device (called a phoropter or refractor) attached to it. The patient looks through the device and focuses on an eye chart 20 feet (6 meters) away. The device contains lenses of different strengths that can be moved into the patient’s view. The test is performed one eye at a time. If the patient is wearing contact lenses, they should be removed before the test.

In case the final vision is less than 20/20 even with lenses, then there is probably another non-optical problem with the eye. The vision level achieved during the refraction test is called the best-corrected visual acuity (BCVA).
 

What Are The Causes of Abnormal Refraction Test Results?

• Abnormal results may be due to:

• Astigmatism (abnormally curved cornea causing blurred vision)

• Hyperopia (farsightedness)

• Myopia (nearsightedness)

• Presbyopia (inability to focus on near objects that develop with age)
   

Other conditions under which the test may be performed:

• Corneal ulcers and infections

• Loss of sharp vision due to macular degeneration

• Retinal detachment (separation of the light-sensitive membrane (retina) in the back of the eye from its supporting layers)

• Retinal vessel occlusion (blockage in a small artery that carries blood to the retina)

• Retinitis pigmentosa (an inherited disorder of the retina)
   

There is an art to refraction and the optometrist will always answer the patient’s questions and as well as discuss their findings. Based on the results of the refraction test, they can determine the amount of myopia, hyperopia or astigmatism.
